Referring to Fig. 1, Fig. 2 and Fig. 9, operation principle of the present utility model is as follows.In the ordinary course of things, natural air enters air purifying room 114 from the natural air inlet port 113 of control cabinet, after sponge filtrate layer 13 and salt sterilization thing layer 14 filtered and sterilizes, it was stand-by at any time through the headroom air chamber 116 that baffle plate 12 enters the below to become pure air.In order to carry out fresh-retaining preserving,, also should make the air maintenance cleaning in the refrigerating chamber 105 except the cold water chamber 103 that must supply with refrigerating box cabinet 1 as previously mentioned causes the low temperature environment with low-temperature cold water to depositing in the refrigerating chamber 105 food products on the food shelves 8 in.For this reason, after having store food products and good seal refrigerated bin door 2 as described above, should (promptly contain dust with unholiness in the refrigerating chamber 105 earlier, bacterium and other microorganism) air extract out and to go, but this moment Closing Switch 24 and open switch 41, allow battery pack 22 give motor 20 power supplies, to pass through pinion 35, gear wheel 36, bent axle 37 and connecting rod 192 drive piston 191, with the unholiness air in the refrigerating chamber 105 by the exhaust fitting 4 on the cabinet 1, pipe 28, the air inlet pipe joint 27 on the casing 11 and the air inlet end 192 of air pump 19 are drawn into air pump 19, discharge outside the control cabinet by blast pipe 26 from its gas outlet end 191 again, bleed cut-off switch 24 and stopcock 41 after a period of time stop to bleed.Then can open switch 61, to allow pure air in the headroom air chamber 116 in atmospheric pressure and refrigerating chamber under hypobaric pressure differential effect, enter refrigerating chamber 105 through net air discharge conection 15, appendix 16, air inlet pipe joint 6, refrigerated air box 9 and air inlet pipe 10, be performed until inside and outside air pressure and equate just to stop.Carry out freezing and further reduce temperature if need to taste with discrimination food on the basis of the above, then can enable micro-blower 18 suffering from indigestion in the refrigerating chamber 105.But this moment Closing Switch 23 and open switch 71, allow battery pack 21 give motor 17 power supplies, the blade rotation of calming the anger with belt driven blower 18, pure air in the headroom air chamber 116 is blasted refrigerated air box 9 through appendix 25, air inlet pipe 7, at first be make the refrigerated air box, then be that the pure airs in the refrigerating chamber 105 are constantly compressed and supercharging, thereby make refrigerating chamber drop to the temperature (0 ℃-2 ℃) of sharp freezing, cut-off switch 23 and stopcock 71 stop cooling then.Damage refrigerator in order to prevent in the refrigerating chamber 105 that superchargings are too high, be provided with emergency valve 40 especially, when supercharging surpassed setting value, air bleeding valve 40 automatic vents were to reduce air pressure.Commercially available or the employing prior art manufacturing of this air bleeding valve.Because heat exchange action, the temperature of low-temperature cold water can slowly raise in the cold water chamber 103, therefore must change every certain hour; Simultaneously, along with the increase of food preservation time, the pure air in the refrigerating chamber 105 also can become unholiness gradually because of the influence of various factors, also need to change.The energy that current are had when making full use of the water that exhaust temperature raises, the utility model specialized designs miniature current air exhauster 29, to reach the water that exhaust temperature simultaneously raises and the purpose of unholiness air.Only need open switch 301 and 51 this moment, allow water in the cold water chamber 103 through the inlet end 291 of drainpipe 32 ingoing stream air exhausters, allow air in the refrigerating chamber 105 through the air inlet end 292 of blast pipe 33 ingoing stream air exhausters, because current have caused the negative pressuren zone of current air exhauster 29 inside, therefore can make unholiness air in the refrigerating chamber 105 under differential pressure action along with current are discharged outside the control cabinets through aqueous vapor delivery pipe 34 from aqueous vapor floss hole end 293 together and constantly, the water of discharge also can be used as cooking and daily washing.

The utlity model has following outstanding advantage: (one) saves the energy. It does not consume AC energy, and battery consumption is also saved very much, takes full advantage of natural low-temperature cold water and makes material of cooling, and is economical and practical, adapts to especially short of electricity and the normal area use that has a power failure. (2) cold storing and fresh-keeping is effective. Because refrigerating chamber employing pure air and cabinet door sealing effect are excellent, therefore prolonged the food products fresh keeping time. (3) reasonable in design. For example the design of current air exhauster is used and is utilized the inner and outer air pressure difference of atmospheric pressure and refrigerating chamber to pass into pure air to refrigerating chamber, has all reached energy-conservation effect. (4) utilization is wide. Not only all kinds of meats, aquatic products, melon and fruit, vegetables, beverage be can preserve, farmers' preservation paddy, wheat, corn and gourd, fruit and vegetable seed etc. also can be used for.
